ROLLING- 'SCREEN.

Application filed August 23, 1924. Serial No. 733,768.

To all whom it may concern.

Be it known that 1, AUGUST H. BECKMAN, a citizen of the United States,and resident of Madison, in the county of Dane and State of Wisconsin,have invented certain new and useful Improvements in Rolling Screens;

. and I do hereby declare that the following facility as the operatingof the window.

In screens as heretofore constructed it has been the customary practiceto provide a sliding panel, but as is well known, this construction ishighly unsatisfactory as the guides for the panel frequently bind and asit is impossible to maintain them in good working condition. Furtherthan this, they are unsightly and detract from the neat appearance ofthe windows.

This invention provides a rolling screen for windows which is ofattractive and pleasing appearance, which is compact, and which ishighly serviceable in operation.

Embodiments of the invention are shown in the accompanying drawings, inwhich Figure 1 is a vertical sectional view through a. window equippedwith a rolling screen, such view corresponding to a section on the line1-1 of Figure 2.

Figure 2 is a sectional view on the line 22 of Figure 1.

Figure 3 is lal fragmentary horizontal sectional view on the line 3-3 ofFigure 1.

Figure 4 is a transverse sectional view through the screen roller.

Figure 5 is a detail of one of the hangers showing the trunnions inposition and show ing the end of the roller,

Figure 6 is a plan view of a modified form of end clip for the bottombar of the screen.

Figure 7 is an elevation of the structure shown in Figure 6.

The drawings show a conventional type of window having sashes 1 and awindow sill 2. It is preferable to rovide this device when the windowsare initially made, and under these condition the upper portion 3 of thewindow frame is extended inwa dly. However, in old styles of windowswhere this device is applied an additional member 3 is provided andsecured in place. This additional member may be positioned either abovethe top of the window casing or directly in front of it, as shown inFigure 1.

Sides 4 are provided, as shown in Figure 2,

and a front, upper, downwardly extending strip 5 is secured in position,as shown in Figure 1. A horizontal bottom 6 is provided which completesthe boxlike compartment at the top, as shown clearly in Figure 1. Thisbottom is provided with a slot 7 adjacent its forward side and with aslot 8 adjacent its rear edge. A vertical partition 9 (see Figure 2) isprovided on each side of the window casing inwardly of the wall 4. Thispartition 9 is provided with a slot 10 through which the narrow portions11 of the end clips for the bottom hair 12 of the screen project. Thebottom portion of the screen 13 is secured to the bottom bar 12 and ispreferably clamped between suchbottom bar and a strip 14, as shown inFigure 1. The end clips are provided as stated, with a narrow or thinportion 11 and are further provided with inwardly extending plates 15adapted to grip the ends of the bottom bar 12 between them, and to besecured thereto by means of screws or bolts, as shown in Figure 2. Theseend clips are provided with outwardly extending tongues 16 within whichthe upper ends of straps 17 are secured, the purpose of such strapsbeing hereinafter described. The screen 13 is wound upon aroller 18.This roller is preferably split, as may be seen from Figures 1 and 4,and the upper end of the screen is secured between the half sections ofthe roller, the sections being secured together in any desired manner.The ends of the roller, (see Figure 3) are provided with small drums 19,which fit over such ends and aid in holding the half sections of theroller together. These drums are provided with outwardly projectingtrunnions 20 which are received in horizontal slots 21 of hangers 22.(See Figures 3 and 5.) The purpose of the elongated slots is to permit=lateral shifting of the roller [as the screen unwinds, so as to preventany sharp angle being formed in the screen adjacent the roller. Thescreen, it will be noted, passes through the slots 10 and 8, andconsequently free motion of the roller is desirable to prevent sharpbending of th screen.

The strap 17 passes downwardly from the end clips of the bottom. bar 12of the screen around pulleys 23 and from thence passes upwardly over thedrums 19. From thence the strap passes downwardly and is looped througha pulley 24% (see Figure 1) such pulley being urged downwardly by meansof a weight 25 or a spring in any suitable manner. The straps 17 passupwardly and are secured to the drums 19. Thus when the screen israised, the strap 17 is pulled upwardly with the bottom bar 12 of suchscreen and consequently the.

straps are unwound from the drums 19 thus winding the screen up. Thescreen will stay at any place where it is set, and may be mosteasilyraised and lowered as occasion demands. There is no possibility of improper manipulation of the screen for the reason that the winding andunwinding operations are accomplished by wholly automatic means and theoperator is merely required to raise and lower the screen as he desires.

In the form of clip shown in 6 and 7 substantially the same constructionis followed as that previously described. In this form, the end bars aresimilarly gripped between the rearwardly extending arms 26 of the clipand a narrow portion 27 is provided corresponding to the portion 11 (seeFigure 2) previously described. This clip is intended for use with acord instead of the flat strap, as shown in 17, Figure 2. It isconsequently provided with an outwardly projecting tongue; 28 providedwith an eyelet portion 29 adapted to receive such cord. A convenient wayof making this clip is to form it from a single fiat strip of sheetmetal and to out two slots in the metal to provide the faces 30 and 31of the tongue.

The upper and lower portions at the fold of this strip, as indicated at32 and 33 (see Figures 6 and 7 are pressed inwardly and are folded, asindicated at 34 (see Figure 6) to provide additional strength andreinforcement for the clip.

It will thusg' be seen that a rolling screen has been provided which maybe most easily operated, which will permit the raising and lowering ofthe screen, which will insure the automatic winding and unwinding of thescreen, which will prevent sharp bends being formed in such screen andwhich is a relat1vely simple and reliable construction.

Although the: invention has been described in considerable detail, it istoobe understood that the invention may be variously embodied and is,therefore, to be limited only as claimed.

I claim: a

1. The combination of a window having a casing, a housing mountedadjacent the upper portion of said casing, a roller positioned withinsaid housing, a screen attached to said roller, a bottom bar secured tosaid screen, a strap extending downwardly from said bottom bar andpassing around a pulley located adjacent the lower portion of saidcasing, said strap extending upwardly and being attached operatively tosaid roller and having a loop formed therein, and a take up memberlocated within said loop and adapted to keep said strap taut and toaccommodate any variation in length there-of during winding andunwinding operations.

2. The combination of a window having a casing, a. pair of side wallspositioned inwardly of said casing and having slots therethrough, ahousing located adjacent the upper portion of said casing, atransvensely -,positioned roller mounted within said housing, a screenextending through said slots and wound about said roller, a pair ofdrums carried by the outer end of said roller, straps wrapped aroundsaid drums and having a looped portion, atake up member in said loopedportion, said straps continuing downwardly and passing around bottompulleys, and extending upwardly, the upper ends of said straps beingattached to' clips carried by the bottom portion of said screen andprojecting through the said slot.

In testimony that I claim the foregoing I have hereunto set my hand atMadison, in the county of Dane and State of Wisconsin.

AUGUST H. BEOKMAN.
